It’s a firmware problem that was side-fixed later in version 6.11 of the operating system. Do the following steps to update the operating system.
If you can’t use the mobile data you can transfer the files by connecting to a computer or through an SD card or a USB stick.
For computer USB connection go to Settings(gear icon on homescreen) and search for USB to activate the File transfer mode.
The SD card fits in a specific slot of the SIM tray where you can alternatively insert a second SIM. Open the tray very gently with the tool, if it doesn’t pop out help it very gently with something very thin like a needle.
You can also use an Ethernet cable with an appropriate adapter USB-C to Ethernet, maybe not everyone will work.
